2040 Comprehensive Plan: Envision Shakopee

LOCAL SURFACEWATERMANAGEMENT PLAN Goals: 1. Limit public capital expenditures that are necessary to control excessive volumes and rates of runoff 2. Maintain or improve the quality of water in lakes, streams or rivers within or immediately downstream of Shakopee 3. Protect and enhance recreational facilities and fished wildlife habitat 4. Educate and inform the public on pertinent water resources management issues and increase public participation in water management activities 5. Prevent erosion and sedimentation to the most reasonable extent 6. Protect the quality and supply of groundwater resources 7. Protect wetlands in conformance with all state and federal requirements 8. Continue to implement an annual inspection and maintenance program as required by the City’s NPDES permit 9. Use available funding mechanisms to construct and maintain a sustainable stormwater management system Implementation: » » The Storm Water Master Plan outlines capital improvement projects which are intended to remedy issues identified as current problems focused on water quality and flood protection » » Operation and maintenance activities related to the NPDES MS4 permit compliance, operation and general maintenance of the City’s drainage system » » City ordinances and policies to improve the quality of surface waters, improve surface discharge and achieve sustainable site development practices should be updated to remain current with watershed district rules and NPDES permit requirements » » Continue to monitor and study surface water resources with projects to collect water resources data such as water quality monitoring projects and other projects to evaluate cost benefits for various storm water treatments or planning opportunities

SURFACE WATER Surface water is water that collects on the surface of the ground which carries surface, street and snow melt runoff from land generally to bodies of open water. Surface water storm sewers are completely separate from those that carry wastewater (sanitary sewers) and municipal water (tap water). Surface water drainage system are designed to protect residents from flooding and remove pollutants from stormwater runoff. The City’s surface water drainage system uses catch basins, storm sewers, streams, ponds, wetlands, lakes, lift stations and ditches to manage all forms of runoff. Stormwater generated from areas within the city is generally directed from the south to the north ultimately into the Minnesota River. The city is divided into seven major watersheds with an additional watershed within a portion of Jackson and Louisville Townships. There are seven major bodies of water which convey and store water within Shakopee; of those seven, three are listed as impaired by the Minnesota Pollution Control Agency. Additionally, there are over 200 wetlands of various sizes and types located within the city. Detailed discussion and information on these issues can be found in the appendix of this Plan in the Local Surface Water Management Plan (LSWMP). The city updated its LSWMP in 2019. The plan describes, in more detail, the components of the city’s surface and stormwater system and defines nine goals to protect the city's surface water. In addition, the LSWMP outlines an implementation plan to help achieve these goals. These are outlined in short in the column to the right.
